I'm in the middle of installing a second battery in the powerboat to run the stereo, radio, etc while at anchor or at the dock. I'm doing the job myself. Just had a few questions. I have the following parts: battery, box, wire, switch, fittings. Is there anything I'm missing? And second, how do I go about mounting the battery box in the boat? It looks like the other one is screwed into the floor (I can't access the underside). I don't have a terrible amount of experience with marine electronics, so any help is appreciated.

Thanks
